The human body contains muscles, bones, blood veins, the brain, lungs, the heart, pigments, etc. The human body is approximately 75% water. It consists of organ systems, which are made up of organs made of tissues made of cells. That's how every complex organism is, except different living things contain different organs because they live in different environments.
